亚马逊FBA备货时间全攻略：从新手到旺季的完整指南
FBA模式的核心流程 | Core Process of FBA Model
FBA（Fulfillment by Amazon）模式是指国内卖家将货物运送至亚马逊指定的海外仓库，由亚马逊负责仓储和配送。卖家需要重点关注的是从国内到亚马逊仓库的运输时间，这个时间包括：工厂发货/采购→贴标包装→国内运输→亚马逊签收→上架可售。
The FBA model means sellers ship products to Amazon's overseas warehouses, with Amazon handling storage and delivery. The key focus is the shipping timeline from domestic to Amazon warehouses, including: factory shipment/procurement → labeling/packaging → domestic shipping → Amazon receipt → shelf availability.
新手卖家备货建议 | Tips for Beginner Sellers
首次使用FBA时，建议使用销量追踪工具分析同类产品数据后再备货。这不仅能帮助了解市场状况，还能优化后续运营计划。
For first-time FBA users, we recommend using sales tracking tools to analyze similar products before stocking. This helps understand market trends and optimize operational plans.
常规备货策略 | Standard Inventory Strategy
一般情况下，备货量应为1个月销量+备货周期内销量。例如手机壳备货周期15天，则需准备45天的销量。后续可根据后台销售数据动态调整。
Typically, stock should cover 1 month sales + sales during preparation period. For example, if phone case prep takes 15 days, prepare for 45 days sales. Adjust later based on sales data.
旺季备货要点 | Peak Season Preparation
旺季（如黑五、圣诞）需提前2-3个月备货，避免因销量激增、物流延误导致的断货风险。断货可能导致购物车丢失和店铺权重下降。
For peak seasons (Black Friday, Christmas), prepare inventory 2-3 months in advance to avoid stockouts due to sales surges and logistics delays, which may cause Buy Box loss and store ranking drops.
关键计算公式 | Key Calculation Formulas
FBA安全库存 = (交货+物流+上架+节假日) × 日销量
示例：(10+8+5+2)×200=5000件
FBA Safety Stock = (Production + Shipping + Shelf Time + Holidays) × Daily Sales
Example: (10+8+5+2)×200=5000 units
备货周期公式 | Inventory Cycle Formula
备货周期=交货+物流+上架+节假日天数
按上例：10+8+5+2=25天
Inventory Cycle = Production + Shipping + Shelf Time + Holidays
Example: 10+8+5+2=25 days
